About this 0.71ct natural radiant diamond

This 0.71ct natural radiant sits in the half to three-quarter carat band, graded D colour (colourless) and SI1 clarity (slightly-included) and certified by GIA 15427979. Listed at 4 retailers as of November 2, 2026, with a relatively tight 13% spread, which is unusual at this carat range and suggests competitive pricing across the listings. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
